THX for help. Another problem which I have, is that system command dnping (which is used in my real aplication instead of ping.exe) to DECnet ping, havn't implemented timeout. So if destination is unreachable the child proccess won't be terminated. To termintate any child procces from their parent after some timeout I can implement some array in which I can save $pid and time() after forking and then I will periodically check in parent procces if this timestamp + timenout is or isn't bigger than time(). But I don't know, if parent can termintate it's children procceses. Also no idea if I can do this by this way. And as adition because qx// do forking for system call, I have to grep pid of dnping proccess and kill it to. Seems really dificult. Or no?

I wil be glad for any help or comment. THX. Litin
